Science & Mathematics - 4 September 2007

On Sept. 8, 2004, the returning capsule of the Genesis Mission (which collected particles of the solar wind) crashed to earth in the Utah desert when its parachute failed to open. The capsule, which was 162 in diameter, hit the ground at 311 and penetrated the soil to 50% of its diameter.

Part A
What was the component of its constant acceleration in , as the capsule penetrated the earth?
Take the + direction to be downward, in the direction of the motion of the capsule.

Part B
What was the component of its constant acceleration in ’s, as the capsule penetrated the earth?
Take the + direction to be downward, in the direction of the motion of the capsule.

Part C
How long did it take the capsule to stop once it hit the ground?


If you could help, I would appreciate it. This is the only one I have left and it is driving me nuts. I can't figure it out. I am not sure if I am really getting what the question is asking. Any help would be greatly appreciated.

I work on a truck with no a/c. I have a 1.5 liter bottle which I don't always drain during the day, but refill and freeze at night. Is there some point at which I should dump all of the water, wash and refill it?

A- multiple experimental variables will make the procedure too difficult to continue
B- the number of experimental variables must match the number of controlled variabes
C- if there’s more than one experimental variable, the outcome may not be clearly attributable to any of them.
D- Results are easier to record with only one experimental variable.

At a space station located at Lagrange point 2 how would we see the Earth and Moon? Would the Earth appear to be stationary? How would the Moon look when it passes in front of the Earth from that persepective? Tiny? See diagram.

If you have a limit and you solve to get 0 over 0, you factor... but what if I have a number over 0? what's the procedure for such limits?

find all values of x or y such that the distance between the given points is as indicated.
(x,7) and (2,3) is 5
if you can show work too, that would be great.
Thanks

I am trying to learn to do math functions using a basic calculator. I know to find sinh, I use the equation sinh(x)=(e^x - e^[-x]) / 2. Now, what can I do to this result to find the arcsinh of x?

And is the procedure the same with the other geometric functions (sosinh and tangent)?

I'm always being asked aren't I 'burning up' because I'm wearing jeans and/or long sleeves. I wonder, at what temperature do people literally 'burn up'? (So I can say, 'Nope, it isn't QUITE xx degrees out.....')

The bible doesn't mention life on other planets? Is it possible that meteors smashing in to the earth thousands or millions of years ago could have cause debris containing life from earth to travel to other planets? Even if it was just bacteria could that bacteria evolved in to species that are surviving on other planets today??
